BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 It is the overall flow chart of the present invention;

[0039] Figure 2 It is a schematic diagram of the prompt volume of the present invention. DETAILED DESCRIPTION

[0040] The following is a clear and complete description of the technical solution of the present invention in combination with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Research has found that in psychology, meditation is a state where humans consciously detach their brains from external consciousness and enter a very calm state. The brain wave signals of humans in a meditative state and a non-meditative state are different, so the meditative state can be reflected through brain wave signals. Most of the existing methods for training users to meditate require manual playback of prompt sound effects. Manual playback cannot reflect the degree of the user's entry into the meditative state through sound effect information, so it is not conducive to users' meditation training.

[0042] In order to solve the above technical problems, the present invention provides a meditation sound effect control method, device, equipment and storage medium based on brain waves, which solves the problem of low accuracy of prompt information used by users for meditation training in the prior art. In specific implementation, the present invention obtains a meditation index (the degree of entering a meditation state) based on brain wave signals, and then obtains sound effect information based on the meditation index. The present invention can improve the accuracy of the acquired sound effect information, that is, the sound effect information acquired by the present invention can better reflect the degree of the user's meditation state, thereby being more conducive to the user performing meditation training according to the sound effect information.

[0043] For example, when a user is doing meditation training, the user's brain wave signal is obtained through existing equipment. For example, at the first moment t1, the user's brain wave signal strength is s1. The strength s1 is the brain wave signal corresponding to the user's low degree of meditation (small meditation index). At this time, the sound effect information with a volume of v1 is obtained based on the meditation index. When the user hears the sound effect information with a volume of v1, the user knows that he is in a low degree of meditation and will adjust himself in time to enter a deep meditation state. On the contrary, when the user's brain wave signal strength is s2 at the second moment t2, the strength s2 is the brain wave signal corresponding to the user's high degree of meditation (large meditation index). At this time, the sound effect information with a volume of v2 is obtained based on the meditation index. When the user hears the sound effect information with a volume of v2, the user knows that he is in a high degree of meditation. At this time, the user only needs to maintain the current state to complete the meditation training.

[0044] Exemplary Methods

[0045] The brainwave-based meditation sound effect control method of this embodiment can be applied to a terminal device, which can be a terminal product with a music playback function, such as a television, a mobile phone, etc. Figure 1 As shown in , the meditation sound effect control method based on brain waves specifically includes the following steps:

[0046] S100, obtaining a user's brain wave signal.

[0047] The frequency band of the brain wave signal collected in this embodiment is 8 Hz to 12 Hz.

[0048] Brainwave signals refer to the electrical signals formed by the sum of the postsynaptic potentials of a large number of neurons when the brain is active. When humans close their eyes and use meditation training to calm their brains, they will experience active brainwaves in the 8Hz to 12Hz frequency band, and the energy value of these brainwaves is high. By collecting and analyzing brainwaves, the meditation activities of the human brain can be detected.

[0049] This embodiment starts collecting the user's brain wave signals after the user has started meditation training for a period of time. For example, the user sits down at time T1 to prepare for meditation training, but this embodiment does not immediately obtain the user's brain wave signals through the brain wave measurement device at time T1, but starts collecting the user's brain wave signals at time T2 after time T1. This is because the user has just sat down at time T1, and the brain is still in a very active state. The brain wave signal at this time does not have any value reflecting the meditation index. If subsequent operations are performed based on the brain wave signal at this time, it will only interfere with the user's entry into the meditation state.

[0050] This embodiment acquires not only the intensity of the brain wave signal but also the frequency of the brain wave signal.

[0051] When the present embodiment is the intensity of the brain wave signal, the present embodiment first obtains the time domain data of the brain wave signal, then converts the time domain data signal into the frequency domain data signal, calculates the signal intensity Y1 in the 8Hz frequency band in the frequency domain data signal, calculates the signal intensity Y2 in the 12Hz frequency band in the frequency domain data signal, and then calculates the difference between the absolute values ​​of Y1 and Y2. The reason for selecting the brain wave signals in the 8Hz and 12Hz frequency bands is that the brain wave signals in this frequency band are suitable for obtaining the meditation index of the user, and the difference between the absolute values ​​of the two frequency bands can better reflect the meditation index.

[0052] S200, obtaining a meditation index matching the brain wave signal based on the brain wave signal, wherein the meditation index is used to reflect the degree of brain activity.

[0053] Different brain wave signals correspond to different meditation indexes, and each meditation index corresponds to a sound effect information.

[0054] Step S200 includes the following steps S201, S202, S203, S204, S205, and S206:

[0055] S201, obtaining a first sound effect in the sound effect information according to the sound effect information.

[0056] The sound effect information includes a first sound effect, where the first sound effect is a noisy sound effect, for example, the first sound effect may be the sound of huge waves.

[0057] S202, obtaining a second sound effect in the sound effect information according to the sound effect information, where the second sound effect is different from the first sound effect.

[0058] The sound effect information includes a second sound effect, and the second sound effect is a calm sound effect, for example, the second sound effect may be the sound of paddling.

[0059] The first sound effect is the sound of huge waves, which is a relatively noisy sound; while the second sound effect is the sound of paddling water, which is a relatively quiet sound. Therefore, the first sound effect and the second sound effect are different.

[0060] S203: Obtaining a first volume corresponding to the first sound effect according to the meditation index.

[0061] In this embodiment, the device can not only control the first volume according to the acquired meditation index, but also control the change state of the first volume according to the meditation index change information. The specific process is: according to the meditation index, the index change information corresponding to the meditation index is obtained; according to the index change information corresponding to the meditation index, the first volume change information corresponding to the first volume is obtained, and the first volume change information matches the index change information.

[0062] The meditation index of this embodiment is not obtained based on the instantaneous value of the brain wave signal, but based on the peak value of the brain wave signal. The specific process is as follows:

[0063] Get a brain wave signal, sample the brain wave signal at a set sampling frequency, get the sampled signal, calculate the peak value of each sampled signal, and fit all the peak values. The specific fitting process is as follows:

[0064] Calculate the average value of all peaks, remove the peaks whose difference with the average value is greater than the set value, and fit the remaining peaks to obtain the fitting curve.

[0065] For example, when fitting the peak value of the brain wave signal, the value of the fitting curve gradually decreases, which means that the degree of meditation of the user gradually deepens, and the first volume emitted by the device also gradually decreases.

[0066] The reason why the present embodiment adopts the fitting curve to obtain the change information of the brain wave signal is that the instantaneous change of the brain wave signal cannot accurately reflect the degree to which the user enters the meditation state, thus avoiding the problem of erroneous prompt volume obtained by using the instantaneous brain wave signal.

[0067] S204: Obtain a second volume corresponding to the second sound effect according to the meditation index.

[0068] S205, obtaining a third sound effect in the sound effect information according to the sound effect information, wherein the third sound effect is different from the first sound effect and the second sound effect;

[0069] S206: Obtain a third volume corresponding to the third sound effect according to the meditation index.

[0070] This embodiment not only uses the first volume but also the second volume and the third volume. Moreover, the device emits the third sound effect only after the brain wave signal reaches a certain value.

[0071] For example, the following example is used to illustrate the detailed process of the entire step S200:

[0072] When it is detected that the user's brain wave signal is gradually weakening, the corresponding meditation index gradually increases, that is, the user's meditation degree gradually deepens. At this time, the noisy first volume can be controlled to gradually decrease, and the second volume can be gradually increased. When the brain wave signal is less than a certain value, the third sound effect starts to play. The third volume corresponding to the third sound effect can gradually decrease as the brain wave signal weakens, or it can remain unchanged. The third sound effect can be a bird's cry.

[0073] S300, obtaining sound effect information corresponding to the meditation index according to the meditation index, wherein the sound effect information is used for meditation training.

[0074] In this embodiment, the smaller the meditation index is set, the more active the brain is, and the larger the meditation index is, the quieter the brain is, and the quieter the brain is, the deeper the user enters the meditation state. There is also data in the prior art showing that there is an inevitable connection between brain wave signals and meditation states. In this embodiment, the meditation index is set to 0 to 100. When the meditation index is 0, the user's brain is in a very active state, that is, the meditation state is very poor; when the meditation index is set to 80, the user enters a state of concentration (the meditation state is very good).

[0075] The device of this embodiment will play the course content sound effect while emitting the prompt sound, and the course content sound effect is used to guide the user to enter the EEG state corresponding to the set meditation index. In this embodiment, the course content sound effect can be played before step S100, or after step S100.

[0076] The detailed process of the method of the present invention is described below with specific examples:

[0077] When the user starts to train the meditation state, the brain wave measurement device is worn on the user's head, and the course content sound effects are played at the same time. The so-called course content sound effects are to tell the user how to enter the meditation state, such as telling the user to close their eyes and breathe slowly, etc. The course content sound effects will continue to play during the whole process. When the training just starts, the first sound effect and the second sound effect are played at the same time. The first sound effect is the sound of huge waves, and the second sound effect is the sound of paddling. Figure 2 As shown, at the beginning of training, the first volume corresponding to the first sound effect reaches the maximum value, and the second volume corresponding to the second sound effect is the minimum value. As the training progresses, the user's brain wave signals are continuously collected. When the brain wave signals gradually weaken, the first volume is adjusted to gradually decrease, and the second volume is gradually increased. When the user hears the first volume gradually decrease and the second volume gradually increase, he knows that his meditation index is gradually increasing, that is, the user is gradually deepening into the state of meditation. Figure 2 As shown, when the first volume is reduced to zero and the second volume is increased to 45%, it indicates that the user has entered the relaxation state among the four meditation states of active, calm, relaxed and trance. When the user cannot hear the first volume, the user knows that he has entered the relaxation state, that is, the user knows that he has obtained a good meditation effect by following the course content sound effects. After that, the second volume begins to gradually decrease. When the second volume is reduced to 20%, the third sound effect begins to play. The third sound effect is the sound of birds. When the user hears the sound of birds, he knows that he has entered the trance state. At this time, the corresponding meditation index is 80. In this embodiment, the first volume gradually decreases, the second volume gradually increases, and the third volume remains unchanged. Such a setting tells the user in the form of a prompt sound which degree of meditation state he is in (the meditation state is indicated by the meditation index), and the existence of the prompt sound will not interfere with the user's entry into the meditation state. The above three volumes cooperate with each other to better help users to conduct meditation training and soothe the user's mood.

[0078] In summary, the present invention converts brain wave signals into meditation indexes, and then controls the sound effects through the meditation index, thereby establishing a connection between brain wave signals and sound effects. The meditation index is the degree to which the user enters a meditation state, which is convenient for knowing the degree to which one enters a meditation state based on the sound effects. In addition, the sound effects of the present invention can also help soothe the user's mood, so as to better perform meditation training. The method of the present invention uses the physiological feature of brain wave signals that correspond to the meditation state to obtain sound effect information, so that the method of the present invention is separated from the subjectivity of the user and uses brain wave signals supported by objective data, thereby improving the accuracy of the sound effect information obtained by the present invention based on the brain wave signals, that is, the sound effect information obtained by the present invention can better reflect the degree to which the user is in a meditation state, thereby being more conducive to the user performing meditation training according to the sound effect information.
